For those, who won`t use the boring "default" landscape textures, I created this addon. It changes the landscapes to a better "spacelook" ingame. Also changed all flowers, the sun and the nightsky, rain and water. 

For using this addon, you must put it into your ressourcepack folder above your ressource-pack.  Optifine (1.20.1) required!
